Silicon nitride grinding balls have excellent features of chemical inertness, low friction and heat generation, electrical insulation, non-magnetic, high strength and corrosion resistance.
Compared with other grinding media, the silicon nitride (Si₃N₄) milling media balls improves energy efficiency, reduces mechanical wear and ultra-fine grinding and dispersion. It is a ideal grinding media when high wear resistance, minimal contamination and less abrasion is required such as semiconductor slurries, pharmaceutical dispersions, battery material milling. Our silicon nitride media balls main size is 0.2 mm - 20 mm.

Frequently Asked Questions
Why Choose Silicon Nitride Grinding Media Balls? How Do They Prevent Slurry Contamination?
With 99% high purity and gas pressure sintering (GPS) at 1800–2100°C, INNOVACERA’s silicon nitride (Si3N4) grinding balls offer exceptional fracture toughness, lower density, and extreme wear resistance. Because they are chemically inert, non-magnetic, and electrically insulating, they eliminate heavy metal shedding, frictional heat buildup, and batch discoloration, ensuring pure and stable nano-dispersion in advanced battery slurries, rare earths, and semiconductor polishing media.
Need High-Purity Milling Media for Advanced Materials? Where Can You Buy Micro and Macro Si3N4 Grinding Beads?
Whether you need ultra-fine micro-beads for nano-milling (0.2–1.0 mm produced by titration/rolling) or larger grinding balls (up to 20 mm formed via cold isostatic pressing), you can buy premium Si3N4 media directly from INNOVACERA. We supply narrow size distributions, tailored bulk quantities, and application guidance to maximize grinding efficiency and lower energy consumption across planetary, sand, and basket mills.
